“H-piles are not always the most efficient option for SOE and often cause too much vibration. For this project, switching to 8" helical piles made the most sense for speed of installation, no vibration and reducing the SOE construction schedule significantly." - Phil Brackett, Deep Foundation Specialist
Subsurface electrical utility work on 7th Street in Brooklyn, New York, initially called for H-piles as part of the SOE.
To reduce disruption on this busy street, the plan was re-evaluated to utilize 8" helical soldier piles, requiring minimal equipment and resulting in significant time and cost savings.
